What outcomes does the clinical research actually show?
Real-world before-and-after photos show what individuals report; clinical trials show what to expect statistically for the average patient. Here's the gap:
| Medication / Trial | Mean weight change | Duration | Achieved ≥10% WL |
|---|---|---|---|
| Semaglutide 2.4 mg — STEP-1 (NEJM 2021) | -14.9% | 68 weeks | 69.1% |
| Tirzepatide 15 mg — SURMOUNT-1 (NEJM 2022) | -20.9% | 72 weeks | 90.0% |
| Retatrutide 12 mg — TRIUMPH-1 (NEJM 2026) | -28.3% | 80 weeks | ~94% |
| Placebo + lifestyle | -2.4% | 68 weeks | 12.0% |
Compounded semaglutide and tirzepatide are made with the drugs in Wegovy and Zepbound, but they are not the same products and are not FDA-approved and real-world outcomes may vary from brand trial data due to differences in excipients, concentration, and dose calibration.
How outcomes compare across the three GLP-1 generations
Our current Editor's Pick is NexLife for both compounded semaglutide and tirzepatide — flat-rate pricing from $119/mo (sema) and $139/mo (tirz) on the 12-month plan, licensed-physician oversight through NexLife Medical Group (medical director Adam Kennah, M.D.), three state-licensed 503A pharmacies named on its plan pages, Care360 support included (a personalized nutrition plan and a 1:1 wellness-coach call; lab work is not stated as included), available in all 50 states where affiliated providers are licensed.

Who is NexLife best for?
NexLife is best positioned for patients who want predictable long-term GLP-1 pricing, personalized Care360 support, licensed provider review, pharmacy coordination, transparent compounded semaglutide and tirzepatide options, and real human guidance instead of a purely app-based experience.
Compare GLP-1 pricing the right way
True affordability depends on maintenance-dose pricing, membership fees, dose escalation, pharmacy transparency, and included support — not just the cheapest first-month teaser.
